MARYLAND, ASSIGNOR r THE BARTLETT MARYLAND, A CORPORATION or MA R Y- GAS AND LIQUID CONTACT APPARATUS Application filed September 14, 1928. Serial 110,305,977.

This invention pertains to gas and liquid contact apparatus and more particularly to apparatus for treating, washing or cleaning a with a liquid.

In general terms, it is an object of the invcntion to improve the construction and ciliciency of operation of apparatus of this character.

Another object of the invention is to pro vide a washer or scrubber having a single compact rotative element adapted to beat or mix the contacting liquids and gases and to propel the gases toward the gas outlet. The rotative element referred to may also be arranged to efiect a separation of the liquid particles entrained by the gases before discharging the gases through the outlet.

A further object of the invention is to provide, in apparatus of the character described,

a screening member so disposed as to control and distribute the flow of the gases and aid in effecting a rapid and complete scrubbing or contacting of the gases with the liquid.

Apparatus embodying the invention is illustrated in the accompanying drawings, wherein,-

Fig. 1 is a side elevational view of a washer having the rotative element thereof pivoted on a horizontal axis, a portion of the external casing being broken away to show the construction of the fan or blower.

Fig. 2 is a cross section taken on the line IIII of Fig. 1.

Fig. 3 is a detail view to an enlarged scale of the adjustable spray nozzle.

Referring to the drawings the apparatus comprises a cylindrical casing 1, which may be cast or constructed in section as indicated, having opposed central inlet openings 2 and 3 for the gases to be cleaned or treated and a peripheral outlet 4; a rotative element 5 carrying beater arms 6 and fan blades 7 and liquid spray nozzles 8 connected through manifolds or chambers 9 to supply pipes 10.

The casing 1 is mounted upon standards or supportin members 11. The rotative element 5 is disposed in the center of the casing l and, being substantially disk-shaped, divides the interior of the easing into two similar sections or chambers. The rotative element is mounted upon ashaft 15 which is supported in any suitable manner, upon the bearings 16 carr1ed bythe central portions of the casing 1. Stufling boxes 17. may

be provided where the shaft 15 passes through the shell of the casing.

Two cylindrical foraminous partitions or screens 18 are arranged on opposite sides of the rot-ative element 5. In the construction illustrated the screens 18 are/supported by the .j'z"

side walls of the casing, but if desired they may be similarly secured to the member 5 to rotate therewith. The screens are symmetrically disposed about the shaft 15 and define gasreceiving chambers 19' adjacent to the inlet openings 2 and 3". Between the walls of the casing 1, thescreens 18 and the rotative member :5 are the washing ortreating chambers 20 in which the beater arms 6 and spraynozzles 8 are disposedf The beater arms 6 are secured in any suit able manner to the rotative element 5 to ro tate therewithand project laterallyfrom the rotative element into the "path ofthc gases traversing the chamber 20. The spray nozs zles 8 are mounted upon the shell of the casing and project inwardly adjacent to. the beater arms 6. v. is

The specific form and arrangement of the beater arms and spray ously modified without. departing from the scope of the inventiomthe latter being preferably adjustable in order that the spray may be controlled. A formof nozzle that may be utilized is shown in; 3. Referring to this figure, the body portion of the nozzle comprises .ahollow slotted or spiral member 21, the inner end of which is in communication with the manifold 9.

It will be apparent" that liquid admitted under pressure tothe manifold 9 will issue through the spaces between the convolutions of the spiral 21 to form a uniformly distributed spray in sheet form around the nozzle throughout its entire length. The outer'end of the spiralQl is closed by a: block 22 car ried on a centrally disposed rod 23. he end of the rod may be threaded, as shown, anda clamping nut 24 provided to engage the block 22. The outer end of the rod. 23 projects nozzles may be vari:

detail in Fig. 63?

through a stufling-box 25 and a bracket 26, and a threaded thumb-nut 27 is disposed on said end of the rod. The thumb-nut 27 is adapted to engage the bracket 26 and thereby exert pressure upon the spiral 2 through the rod 23' and block 22 to alterthe spacing between the convolutions of the spiral through which the washing fluid issues. Such construction throws out the spray in spiral sheet form and opened wide to clean themselves; as well as the adjacent elements. In this way clog-.

ging up of the apparatus is prevented.

The rotative member 5 carrying the beater arms 6 extending into the chamber 20 is also provided at its periphery with fan blades 7 conforming in shape'to the outline of the casing. The casing however extends beyond the fan blades and forms a gas-receiving pocket 28 extending around the entire periphery and merging at the bottom into the outlet '4. The tips of the fan blades are bent, as shown in Fig. 1, to deflect and discharge the particles of water or washing liquid contained. 7 in, the gases laterally through the openings 29 into the channels or recesses 30 which may be cast integral with the casing. Drainage from the channels 30 isipermitted by the trapped pipes 31, and

from the pocket 28 by the sump. 32 .and-

trapped pipe 33.

In operation, the gases to be treated or washed are drawn through the inletopenings 2 and 3, the gas-receiving chambers 19 and the washing chambers20, and'are propelled into the pocket 28 and the outlet 4: by the fan blades 7. The screens 18 serve to distribute the gasesflowing into the washing chamber 20 and, being wetted by the spray from the.

nozzles 8, facilitate the washing of the gases. In the chamber 20 the beater arms (imoving adjacent to'the nozzles 8 serve to efi'ect a thorough commingling of thegases and washing liquid. As the gases are driven through the washer and into'the pocket 28,'the moisture contained therein is separated by the action of the bladetips' and removed through the channels 30.

Various modifications in the arrangement of parts and details of construction may be made without departing-from the scope of the invention as defined by the appendedv claims.

What is claimed is: Y

1. In a gas washer, the combination of a casing provided with a central gas inlet and a peripheral gas outlet, a screen located ad a cent the gas is drawn, avrotative member in the casing provided with fan blades acting to draw the ases through said screen and casing and the spirals may be through said outlet, said rota beater arms on the rotative member for washing the gases after they pass through the screen.

2. In a gas Washer, the combination of a casing provided with a central gas inlet and a peripheral gas outlet, means in said casing for washing the gases admitted through said inlet, a screen interposed between said washing means and. said. inl t, means n said casing; outwardly of the washing -means, 'for forcing the gases radiallytherethrough from said central inlet and means adj acent'the periphery of the casing for elimimating moisture from the gases.

' 3. In a gas washer, the combination of a casing provided with two opposed central gas inlets anda peripheral gas outlet, a rotative member in the casing defining parallel gas passages from the respective inlets to the outlet and of said blades being bent, means in said casing for washing the gases and channels formed in said casing opposite the tipsof said fan blades to receive the moisture deflected thereby from the gas stream.

In testimony whereof I have signed my name to this specification.
